I just had to this. There are a couple additional things that had to come into play for this to happen. YOU had to be too close to the guy in front of you, or you just waited too long to change lanes. Either way, you were in danger of hitting the car that was turning. Next, I'm going to bet that if you changed lanes fast enough that this happened without the guy behind you seeing the car in front of you, it could easily be considered wreckless operation. Just my opinion, I'm not calling you names, saying you're dumb, or anything, just think about what I said, instead of just reacting to it. It got me 5 points off on my driving test!
